Thanks for your help on this.
No. The charger light is off the entire time. I haven’t seen it go on since I bought it. I guess it could be the charger. The battery was driving the motors just fine before it needed charging and I built the robot in June 2014, which is when I also bought the charger. I don’t know why it would be bad I’ve only tried to use it a few times with no results. Should I purchase a new one?
The charger makes a buzzing sound when it’s charging, but no light.

Additional info: the way I tested it is by touching the red and black battery wires directly to the motor terminals. The motor runs for a few seconds and then stalls, and then the battery voltage drops. Next, I take the wires off the motor terminals and measure the battery voltage with a volt meter and I see the voltage gradually start increasing again. Weird.
